From e51e043d927778ee33f0cdb46ad4c70ee1083da3 Mon Sep 17 00:00:00 2001 From: John Morrissey <544926+tachyon-beep@users.noreply.github.com> Date: Fri, 26 Jun 2026 15:40:03 +1000 Subject: [PATCH 01/33] fix(posture): read_floor fails closed on a chain-integrity break read_floor() now gates on verify_integrity() before returning the floor, so a raw-DB-written/forged tail record that breaks the keyless hash chain can no longer silently set the routing floor (it maps to the fail-closed structured default). Cryptographic operator_sig verification stays the operator-side doctor check (KEY_RESET-acknowledgment path only); a recomputed-chain forgery remains the conceded raw-file-write residual (README.md:137). Retires test_read_floor_uses_tail_read's 'must not call read_all' premise (the integrity gate supersedes it) and corrects the now-false module docstring. Closes the load-bearing half of legis-476ab6f125 (PRD-0005 criterion 1).

non-circular oracle; reverse producer obligation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the hand-rolled flat golden with real warpline.impact_radius.v1 / warpline.reverify_worklist.v1 envelopes live-captured from warpline-mcp 1.2.0 (legis repo, HEAD~1..HEAD, 2026-06-27). Add machine-readable provenance marker (_provenance.source = "live-captured") with a CI-visible test that fails if "pending-live-capture" is committed without the escape env var. Rewrite the oracle: deleted HttpWarplineClient/_decode_json_response imports removed; all assertions now flow the golden through WarplineMcpClient._call (schema/ok/meta/completeness validation is real), asserting HARDCODED literals (schema=="warpline.impact_radius.v1", completeness=="NO_SNAPSHOT", affected==[], meta.local_only==True, etc.) — never a re-parse of the golden. Layer-2 recheck repointed from the obsolete REST path to the MCP contract fixture path.

Golden's reverify_worklist was already byte-identical to the freshly captured structuredContent; GOLDEN_BLOB_SHA unchanged. Updates PROVENANCE.md to document both halves are now live-captured with committed transcripts. MINOR (b): make text=False explicit in StdioMcpInvoke's subprocess.run call (was implicit via the absence of text=True; explicit kwarg prevents a future refactor from silently switching to char mode). MINOR (c): add test_content_text_fallback_parse — exercises the content[0].text parse path in StdioMcpInvoke when structuredContent is absent from the result.

The keyless hot read proves **integrity + tail-kind** — NOT operator authorization. Cryptographic `operator_sig` verification under the epoch key stays the operator-side `doctor` check, but note its true scope: `doctor` verifies `operator_sig` only in `_transition_acknowledges` (`doctor.py:649`), reached only via `check_posture_key_reset` (`doctor.py:677`, which early-returns "no key-epoch reset" at `:707` when there is none) **when there is a `KEY_RESET` to acknowledge**. A file-write attacker who *recomputes* the keyless chain on a forged floor-lowering `TRANSITION` of a **non-rekeyed** ledger is therefore caught by **neither** this hot read **nor** `doctor` today — it is a pure conceded raw-file-write residual (`README.md:137`), pinned by an explicit characterization test, not implied-closed. + +**Tech Stack:** Python 3.12, SQLAlchemy Core over SQLite, `uv`, pytest.

This plan adds the missing owner: a `ProtectedGate.transaction()` `@contextmanager` that wraps `self._store.transaction()` and, after commit, calls `self._anchor.update(*self._store.get_latest_sequence_and_hash())`. It is a near-verbatim mirror of the sign-off precedent. + +**Threat reality (state it honestly — this is a DOUBLY-LATENT/preventive fix, not a live-exploited path):** grounding the current callers shows **no code path batches protected appends today, and production wires no anchor at all**. `route_findings` (`route_findings` spans `wardline/governor.py:46-177`; `txn_owner` is chosen at `117-122`) sets its `txn_owner` to `signoff` or `engine` and routes only BLOCK_ESCALATE / SURFACE_OVERRIDE / SURFACE_ONLY — there is **no protected cell in the governor**. Both transports **construct `ProtectedGate` with `anchor=None`** (the constructors at `api/app.py:376-379` and `mcp.py:266-269`) and call `operator_override()`/`submit()` outside any batch. So today the gap is *doubly* latent: the `_record_signed` anchor guard at `protected.py:291` never advances anything because **the anchor is absent (`None`), not merely unadvanced**, AND no caller opens a batch around a protected append. The exposure the finding names is a *future* deployment that both wires an anchor AND wraps a protected append in an `AuditStore.transaction()` with no owner to advance the anchor — for which there is currently no safe API. This fix supplies that API (parity), so the value is **entirely preventive**. + +**PRD-0005 overlap question — RESOLVED by grounding:** PRD-0005 flagged a possible "shared store-transaction wrapper used by both posture and protected."

The hub interface-lock SEAM 4 §4A pins the seam to "*same wire shape as `warpline_impact_radius_get`*" (the envelope), and **GV-LG-3** requires legis to read `meta.local_only`/`meta.peer_side_effects` off that envelope (the flat shape has no `meta`). So the transport becomes **MCP-stdio** (owner-confirmed 2026-06-26): a subprocess speaks JSON-RPC over stdio to `warpline-mcp`, calls one tool per verb with `rev_range=".."`, and returns the parsed envelope. The fix preserves the seams that are CORRECT: the `WarplineClient` Protocol (`impact_radius`/`reverify_worklist` → dict), the injectable-transport pattern (today `fetch`; now an injectable `invoke`), and `read_warpline_preflight`'s fail-safe discipline (`service/preflight.py`: `None`/`WarplineError` → `unavailable`, never an empty affected-set). + +**Threat model shift (HTTP → local process):** the HTTP SSRF / redirect / TLS surface (`_validate_base_url`, `_is_loopback`, `_open_no_redirect`, `_NoRedirectHandler`, and the filigree-clone test) is **moot** and is removed. The new surface is local-process: (1) **no shell, list-argv** — `rev_range` travels as a JSON-RPC *param*, never as a CLI argument, so `shell=False` + a list `argv` makes argument/shell injection structurally impossible (note: `WARPLINE_MCP_CMD="warpline-mcp"` IS an implicit `PATH` lookup — `shell=False` eliminates *shell* injection, not PATH ambiguity; **recommend an absolute path**, and reject an empty command); (2) **output bound** — `subprocess.run` buffers stdout, so the size check is **post-capture + timeout-bounded** (a true *incremental* read bound requires the Popen variant — see Task 2's escalation note; the cap is on **bytes**, `text=False`); (3) **timeout** — bound the child (10s) and let `TimeoutExpired` → `WarplineError`; (4) **isolation** — a missing exe / crash / non-zero exit / garbage / oversize / timeout is a `WarplineError` → `unavailable`, never an escape, and the error carries the child's `returncode` + truncated `stderr` for operator diagnosis. + +**Tech Stack:** Python 3.12, stdlib `subprocess` + `json` (NO new dependency — legis's sibling-client ethos), `uv`, pytest. + +**Prerequisites:** +- Work on a feature branch / worktree, NOT `main` (e.g. `git switch -c fix/warpline-preflight-mcp`).

(2) protected records committed inside an external batch leave the HeadAnchor at the pre-batch head, so truncation back to a stale anchor goes undetected; (3) `policy_boundary_check` scans attacker-supplied absolute roots *outside* the source boundary, leaking arbitrary tree contents/parse results. **Desired outcome:** each path authenticates its input or fails closed — the surface returns to Legis's defining property, "no provable false-green;

Tests cover 3 positives, 3 discriminator-negatives, 8 constraint-negatives, 1 format test (with load-bearing rfc3339-validator assertion), and 1 drift guard (structural equality of prompt's embedded schema block vs committed file, stripping non-validating descriptions only).

feat(service): add read_governance_for_sei, gate wrapper, unavailable helper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the per-SEI governance-clearance projection (`read_governance_for_sei`), the CLI/batch verified-gate wrapper (`read_governance_for_sei_gate` — mirrors `evaluate_override_rate_gate` so both verify halves are mandatory), and the shared unavailable-envelope helper (`governance_read_unavailable`) to `service/governance.py`. Exports all three from `service/__init__.py`. Includes `_POSTURE_BY_KIND` and `_is_rfc3339`; unknown-kind / bad-as_of records are omitted (asymmetric-error), not fabricated. TDD red→green: 10 tests in `tests/service/test_governance_read.py`, mypy clean.

Key properties: - BOTH-objects fail-closed pre-gate (mirrors attestation_get): gates on BOTH runtime.protected_gate AND runtime.trail_verifier; missing either -> status:"unavailable" (discriminated), never silent checked/[]. - Handler calls read_governance_for_sei(_governance_trail_records(runtime)) which runs BOTH verify_integrity (chain) AND TrailVerifier.verify (sigs) via the verified_records path; tampered trail -> AUDIT_INTEGRITY_FAILURE. - outputSchema built via _one_of over the v1 clearance_record fields (sei/disposition/posture/authority/as_of/reasons/content_hash), NOT attestation_get's fields. - Registered in _AGENT_TOOLS, tool_definitions(), and _TOOL_HANDLERS. Tests: - tests/mcp/test_governance_read_tool.py: handler tests (checked/unavailable/ tamper) incl. BOTH-objects gate on each missing half. - tests/mcp/test_output_schema_conformance.py: two explicit variant cases (checked + unavailable) validate against the declared _one_of outputSchema. - tests/conformance/test_governance_read_oracle.py: FROZEN GOLDEN mirroring test_warpline_attestation_oracle.py; byte-pinned blob SHA + LIVE==FROZEN value assert (not schema.validate); both clearance kinds pinned; content_hash cross-check confirms same records as the attestation golden. - tests/conformance/fixtures/legis-governance-read.golden.json: committed golden (blob SHA 898fd1a8c159cd717b0b976a5488b5c0c65a86a6). - tests/mcp/test_server.py: update hard-coded tool list to include governance_read.

Fixes case (d) in the test, which previously asserted "verification failed" (a substring only of the service gate's AuditIntegrityError message, not the contract marker).

ADVISORY ONLY, enrich-only: this read never changes a Legis policy/governance decision. Tests pin it: a byte-identity test proves a hostile Plainweave client cannot perturb a real verdict; a structural test proves no verdict-path function references runtime.plainweave; a GV-LG-3 test refuses any producer claiming governance_verdicts; the honest-degrade path (absent -> unavailable; ok:false error envelope -> unavailable) is pinned. Conformance oracle drives legis's real parser over a frozen golden built from the producer contract (CONSTRUCTED, not live-captured — the hub session's MCP wiring misroutes Plainweave; live end-to-end capture is a flagged follow-up in a legis-rooted session).

The advisory boundary is preserved (warpline never gates; GV-LG-1 stays asserted) — this is a **federation-seam-quality** bet, NOT a north-star governance-honesty item (it fails safe; legis governance is byte-identical with/without the consumer). Validated by a 7-agent ultracode plan review (CHANGES_REQUESTED → all 8 must-fixes folded in, including a **Critical CLI false-green**: the CLI verify path used `TrailVerifier.verify` which lacks the hash-chain contiguity walk), a serial subagent-TDD build, a final opus whole-branch review (READY_TO_MERGE), my independent gate run (1335 passed, coverage 92.39%, floors hold), and a **mutation-proof** that the chain-tamper guard is load-bearing (neutering `verify_integrity()` flipped the CLI to a `checked`/`[]` false-green; the test caught it). + +## Reversal trigger +- If warpline (or any consumer) needs **in-flight / uncleared** governance context (open sign-offs, BLOCKED verdicts) → `governance_read.v2` (ADD, never mutate v1) + a new PDR.
